Couple more quick pics. The oil cooler looks a lot newer than the engine, the dirt on the fins is normal after years of use. It will get completely cleaned and tested. It's very important to have these flow-tested, some people only have them pressure-tested for leaks which can let a massive internal blockage go un-detected. Then the car over-heats in the middle of the desert or going over a mountain and the owner does not know why.
These are of course push-rod motors, the PRs are very interesting with what looks like aluminum in the center for weight-savings. Older ones had wood centers. Those crazy Krauts.
